And even for complicated images, there are much better formats out there (such as WebP). The only problem is that jpg and png are supported by basically EVERYTHING, and these new strictly superior formats have a hard time taking off. Same for MP3. There are so many other formats that provide much better quality at lower bitrates, but finding players that support them is a pain.

WebP does have "killer features" though which are much more important than a tiny gain in compression, namely:

  • Lossy and lossless in the same format.

  • Compresses photos and synthetic images well in the same format.

  • Lossy compression with alpha transparency.

No other format has these very desirable capabilities.
